I was interested in the increase in attendance for regular season home games so I went to the Big Sky Conference website and found attendance data. The archived data started in 2001. In the figure below I used only regular season, home games played at old Woodward Field and Roos Field.
The figure below shows the home attendance with the Montana schools broken out from the average of all other opponents in each year. It shows what most long term fans already know, the GRIZ games have historically filled the stadium and a lot of the extra attendance was likely from GRIZ fans. However, since 2010 (beginning of red turf era and National Championship) there is a significant increasing trend in home attendance for the non-GRIZ games, including a significant bump for the Bobcat games. Bottom line is that attendance for non-GRIZ/CAT games has increased significantly following the red turf/National Championship season.
These improved attendance numbers are great but it makes me wonder,
1) How many potential fans are being turned away from attending home games because the stadium is at capacity?
2) If the stadium was improved, improving the fan experience, how many additional fans from the greater Spokane region would attend the home games?
3) What is the threshold attendance that would balance the cost of stadium improvement with the revenue generated by a larger fan base?
